Solution Overview

Problem

Current spectrum sharing technologies do not effectively manage three-tiered shared spectrum architectures and lack mechanisms for determining the quality of operation, leading to inefficiencies in spectrum utilization and management.

Innovation Solution

A Shared Spectrum Manager (SSM) organizes spectrum segments, communicates with access users of varying priorities, and uses message exchanges to request, bid for, and manage spectrum, ensuring quality of access (QoA) through mechanisms for reassignment, pricing, and handling priority access users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a two-tiered shared spectrum architecture is used, then spectrum sharing is implemented, but it cannot effectively manage three-tiered shared spectrum architectures

Engineering Contradiction:
Improvespectrum architecture compatibilityVSAvoidmanagement system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The Shared Spectrum Manager is designed to handle multiple tiered spectrum architectures (two-tiered, three-tiered, and other configurations) through a unified management framework. The SSM can dynamically adapt to different access user types (incumbent, priority, general authorized access) and spectrum sharing scenarios, making the system universally applicable across various architectural configurations without requiring separate management systems for each tier structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If current spectrum sharing procedures are used, then basic spectrum allocation is achieved, but mechanisms for determining quality of operation are lacking

Engineering Contradiction:
Improvequality of operationVSAvoidmanagement mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements comprehensive feedback mechanisms where access users report quality of operation metrics (such as signal quality, interference levels, and service performance) to the Shared Spectrum Manager. The SSM continuously monitors these feedback signals and uses them to dynamically adjust spectrum allocations, power levels, and access permissions. This closed-loop feedback system ensures reliable quality of operation by continuously optimizing parameters based on actual system performance and user experience.

Inventive Principle:
Principle #23Feedback

3Productivity

If spectrum is shared among multiple users with different priorities, then spectrum utilization is improved, but management and allocation complexity increases

Engineering Contradiction:
Improvespectrum utilizationVSAvoidallocation management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The spectrum resource pool is segmented into different classes based on access user priorities and service requirements. The system divides spectrum into incumbent-protected bands, priority access bands, and general authorized access bands, each with specific allocation rules and management policies. This segmentation allows the Shared Spectrum Manager to apply different allocation strategies to different spectrum segments, simplifying the overall management complexity while maximizing utilization across all user types through targeted resource distribution.

Inventive Principle:
Principle #1Segmentation

AI summary

Methods and apparatus for shared access systems may be used to allow operation in three-tiered shared spectrum architecture. For example, a Shared Spectrum Manager (SSM) may organize spectrum segments. The SSM may communicate with access users of different priority and may use message exchanges to request spectrum, bid for spectrum, manage spectrum, or the like. The SSM may manage admission of access users (allocation of spectrum to users) and operation with a spectrum request that may be provided as a range between a minimum (guaranteed) and maximum quality of operation. The SSM may also manage the way an access user may use the assigned spectrum. Inter-SSM communication may be used in regions where multiple SSMs may exist (e.g. country borders). Accordingly, triggers for this inter-SSM communications and corresponding actions are also disclosed herein.
